' 19%. Serial The present invention relates to sliding door fittings.

More particularly the present invention relates to fittings for sliding doors of railway freight cars. The present application constitutes a division of application Serial No. 42,639, filed July 10, 1925, by the present'appl'icants.

An object of the present invention is to provide a construction applicable to the sliding doors of railway freight cars, whichconstruction will guide the bottom of the door,

which will be sturdy,'and which will effectually shed water. 7

A further object is to provide an improved sliding door mounting for cooperation withcar frames of usual construction.

A further object is to provide a sliding door mounting of improved simplicity and sturdiness over prior practice.

A further object is to provide a sliding door construction which will withstand the effects of weather in an improved manner over prior practice.

Further objects will appear as the description proceeds.

Referring to the drawings Figure 1 is a fragmentary view illustrating part of the side of a railway box car showing the upper part of a sliding door applied thereto;

Figure 2 is a sectional view taken along the plane indicated by the arrows 22 of V Figure 1;

Figure 3 represents a detail of construction' Figure 4 is a view similar to Figure 1 but showing the lower part of the sliding door;

Figure 5 is a sectional view taken along the plane indicated by the arrows 5-5 of Figure 4; and

Figure 6 is a perspective view illustrating a detail of construction.

The numeral 1 indicates the side wall of a railway box car, and the numeral 2 indicates a sliding door. Attached at the top of the sliding door 2 are the brackets 33, which provide supporting means for the rollers 4et. Said rollers bear on the upper surface of the track 5. Said brackets 33 also pro- Serial No. 42,639. Divided and this application filed September 20,

vid'e supports for the rollers 66 adapted to bear against the under side of the track 5, whereby to limit upward movement of the door 2 and prevent sticking of said door.

The numeral 7 indicates a structural steel member which meets the standards of the American Railway Association for side plates for railway cars. Said structural steel member takes the form of a Z- b'a-r having the vertical-lyarranged forward flange 8. The track member 5 is riveted to said forward flange 8 of the structural steel member 7. Said track mei'nber 5, which is shown in perspective in Figure 8, comprises the flanges 9"and 10, which a'redisposed substantially right angular relationship relative to one another.- The flange 9 is adaptedto abut against the outer surface of the flange 80f the structural steel member 7. ;The flange 10 occupies a substantially horizontal position. Dependi ing from the under side of the flange 10 in termed-tats of the width thereof is the flange 11.: I I

Mounted uponthe upper edge of the door 2 is the Z-bar 12, having the upwardly extending flange l3 lying back of the flange 11 of the track member 5. The forward flange 1.4 of the Zrbar 12 lies along the front surface of the door'2 at the upper extremity thereof, and is riveted to the brackets 3-3.

Mounted at the bottom of the door 2 is the T-shap'ed structure 15 having the leg por ti0n 15 underlying the bottom edge of said tending flange 11 of the track. member 5 and with the brackets 18, respectively, .to limit outward movement ofthe door 2.

' ihttenti-onis directed to the structure at the bottom of the door. 2, w-hich structure is shown in detail-inFi-guresi 2,4, 5 and 6. It hasbeen common: practice heretofore to provide a;

Z-bar at the bottom of a sliding door to protect same, one flange of said Z-bar beingdisposed on the outer surface of the door, and the other flange extending downwardly and forming a keeper means for the door. This prior construction has been 'open to the objection that water will find its way between the Z-bar referred to and the bottom of the door, resulting in the rapid deterioration of the door. According to the present invention, a construction is provided which avoids the forming of arpocket for the seepage and collectionof water. Arranged at the bottom corners of the door are a pair of gussets 19,

. and arranged midway between said gussets 19 is the plate or plates 20, said gussets 19 and plate or plates 20 being bolted to said door and to the T-shaped member 15 by means of bolts 25-25. Each of said plates 20 is provided with a flange 21 at its bottom portion, which flange has an upturned tongue22 fitting within a corresponding aperture 23 in the leg-portion 15 of the T-shaped structure 15. By reason of this construction a sturdy structure is had which is not only very well adapted towithstand the shocks encountered in service, but which will minimize deterioration due to the water. .The reason for the minimizing of the effects of weather above referred to will be obvious when it is considered that except forthe relatively small region covered by the gussets 19+19 and the plate or plates 20, the outer surface of the door presents a clear shedding surface which will avoid the collection of water. It will be clear that sliding movement. of.

the door 2 may be accomplished with a minimum of friction, by reason of the rollers 44. The track member 5 may be readily secured to the structural steel member 7,.

which meets the standard of the American Railway Association. Said track member 5 not only provides a convenient bearing surface for the rollers 44, but also provides the downwardly extending flange 11 for cooperabottom rear edge of said door being set into one of the angles of said T-shaped structure, a flange of said T-shaped structure being adapted to cooperate with the guide means on said frame, and a holding member mounted upon the outside of said door and having interfitting engagement with said T-shaped structure.

2. A railway car comprising a car frame and a sliding door, said car frame having attached thereto overhanging members for limiting the outward movement of said door, said door being provided with a pair of structural steel members adapted to cooperate with said overhanging members, one of said structural steels members having a re-entrant angle receiving the bottom rear edge of said door, the other of said structural steel members comprising a plate having interfitting engagement with said first mentioned structural steel member and bolted to said door.

3. In combination, the frame of a railway car, a sliding door, guide means mounted upon said frame, a guide member mounted on the bottom of said door, said guide member having a reentrant angle, the bottom rear edge of said door being set into said reentrant angle, and a holding member mounted on the outside of said door and having interfittingengagement with said guide member.
